Once you've completed The Two Rings, enter the shrine. Here, you must get two orbs to fall into the receptacles on the right and left in front of you.

Stand on the left switch first, causing an orb to drop down into the receptacle on the right. Getting the next orb into its spot is a little trickier.

Stand on the switch to the right to release another ball. Quickly stand on the switch to the left to change the direction of one of the moving parts, then the right switch again once the orb passes that section to get it into the empty receptacle.

This will cause the bars blocking the monk to raise. Before you exit, paraglide to the mechanism across the room to find a chest with a Great Thunderblade. Use step on the switch there to activate a new moving platform that takes you back to the entrance, where you can claim your Spirit Orb.
